The thing is Smoo that when these things are installed they are always pre set as active and have to be coded to turn certain things off for specific models, they don’t put a different part in the car that doesn’t have that option as standard it would cost too much to make different versions of everything they just turn it off before it goes out of the factory so there is no way that they couldn’t turn it back on but whether they have the knowledge to do that or not is down to how thick the specific technicians are at your local dealer!
Craig at GasGuzzlers in Barnsley could do it in 5 minutes for you so it can be done, he did all sorts for me on my Alhambra that has the same system.
